Hey guys so I am more building my rx8 into a show car and was looking to do a BBK that would not only be a bit cheaper than the run of the mill BBK kits, but also to get a full set of calipers that are in yellow.

You can find CTS-V calipers reasonably priced even new and considering pulling the trigger.

First I know that I will likely do a mounting bracket adapter of some sort that is not an issue.

The issue I am seeing is the CTS-V is a 5x120 bolt pattern. Obviously the RX-8 is 5x114.3 so in theory I will just need to find a 380mm front rotor and a 365mm rear roor (CTS-V rotor sizes) in a 5x114.3 and make the caliper brackets center onto the rotors? Or is there a possiblity to take the rotors to a machine shop and machine a 5x114.3 into them? Not sure if having two bolt pattern holes in a rotor is good (or safe)

The other route to go to a two piece front and rear rotors, but that is extremely expensive. But I consider it the last resort.
